  产品实用材料采用耐腐蚀不锈钢。 H71 Wafer Lift Check Valves are made of corrosion-resistant stainless steel. It can be installed on the pipeline at any position to prevent the medium from flowing backward. The boiler water supply system can be returned. The connection method is to use the flange clamps at both ends of the original pipeline to put it into operation. Its indicators are better than any kind of back valve currently on the market. 运用范围广泛,水、汽、油、酸、碱液、氢、氨、特别消防管道等介质均可使用。 H46 double flap check valve has a wide range of applications, such as water, steam, oil, acid, lye, hydrogen, ammonia, special fire pipes and other media can be used.
